We build an equilibrium model of prostitution where clients and sex workers choose to demand and supply sex under three legal regimes: prohibition, regulation and laissez-faire. The key feature is the endogenous evolution of the risk as a consequence of policy changes. We calibrate the model to...

We derive a set of optimal environmental regulations in the presence of asymmetric information about pollution abatement costs, where compliance may have to be induced through appropriate monitoring and enforcement measures. The regulator commits to monitoring of compliance with incentive...

We study a supply chain model where competing manufacturers located around a circle contract with privately informed and exclusive retailers. The number of brands in the market (determined by the manufacturers’ zero profit condition) depends on the level of asymmetric information within supply...

We revisit the choice of product differentiation by competing firms in the Hotelling model, under the assumption that firms are vertically separated, and that retailers choose products’ characteristics. We show that retailers with private information about their marginal costs choose to...

The finance literature views perks either as productivity enhancing expenditures or as a result of poor managerial control by shareholders. Using a corporate jet to attend a business meeting may be justified because of the returns generated for the firm; but flying on the same jet to reach a...

This note shows that, by reducing agency costs, an environmental regulation may enhance pollution-reducing innovation while at the same time increasing firms'private benefit.

Multiple bank lending creates an incentive to overborrow and default. When creditor rights are poorly protected and collateral value is volatile, this incentive leads to rationing and non-competitive interest rates. If banks share information about past debts via credit reporting systems, the...

We analyze the effects of judicial errors on the innovative activity of firms. Successful research investment allows to take a new action that may be ex-post welfare enhancing or welfare decreasing (illegal). Deterrence in this setting works by affecting both the incentives to invest in research...
